CAR-COUPLING.

Specification of Letters Patent.

Patented Sept. 8, 1908.

Application filed April 3, 1906. Serial No. 309,626.

To all whom it may concern:

Be it known that we, ALBERT P. GoLDMAN and HOWARD H. STEPHENS, citiZeI1Sof the United States,residing at North Ohillicothe, in the county ofPeoria and State of Illinois, have invented a new and useful Im rovementin Car-Couplers, of which the fol owing is a specification.

This invention relates to a car coupler, and

the object of the invention is a coupling which cannot when broken ordisengaged, drop down or interfere in any way with the running gear ofthe cars.

Another object of the invention is a coupler in which co-acting artswill be revented from slipping ast eac other, whi e coupled by reason oft e unevenness in the height of the cars, or irregularity in the roadbed.

Still further objects of the invention are to provide a coupler in whichall strain is reknuckle closed and locked. Fig. 3 is a detailperspective view of the knuckle. Fig. 4' is a detail perspective view ofa lock adapted to cooperate with the knuckle. Fig. 5 is adetail persective view of a combined operating pin and atch. Fig. 6 is a horizontasection taken lengthwise through the coupler head and a portion of thedraw bar and showing the knuckle and locking means in plan. Fig. 7 is asection on the line 7-7 of Fig. 6, showing the position of parts locked.Fig. 8 is a section on the same line looking in the opposite direction.Fig. 9 is a section on the line 9-9 of Fig. 6.

In these drawings A represents a draw bar provided with a coupler head Athe front face of which is provided with a concavity A and this frontconcaved face is recessed as shown at A, in Fig. 2 the said recess beingadapted to receive a suitable knuckle. A vertical slot A opens upwardlythrough the top of the coupler head A and at its lower end communicateswith the recess A The coupler head is provided upon one side of theconcavity A, with upper and lowerlugs A and a l nu -klcB is providedwith a perfo- .which projects forward rated cylindrical bearing portionB which is journaled between the lugs A and 1s held in place'by asuitable pin D whlch passes through the lugs A and through theerforations of the bearing portion B of the nuckle B. The bearingportion B is provldedw th a finger B which is formed upon its inner facewith an inwardly projecting portlon B midway its ends, and at its endthe finger B carries a projecting shoulder B whlch extends outwardly.

' A co-acting locking member C rests loosely within the recess A of thecoupler head A, and the locking member 0 is prov1ded with a forwardlyprojecting angled hook portion C slightly recessed upon its upper edgeas shown at C The said locking member is also provided with a s( uaredshoulder C ly parallel to the main body of the hook portion C andparallel to and adjacent the recessed portion C An operating lever andlatchE is cut away adjacent its upper end to form a shoulder E,

and the end portions of said latch are perforated as shown at-E to forman eye. We

also slot the rear face of the locking member C as shown in Fig. 6, atC, and the operatin lever-E is pivoted to the locking member 6 in theslot C To prevent the knuckle B from swinging entirely out of thecoupler head, it is provided with a raised shoulder B which acts as'astop, when the coupler is thrown into 0 en position by engaging theupper inner e go 0 the front wall 0 the recess A A cross strip couplerhead A D is secured within the extending from the front'to the rear andrearwardly and upwardly, and

this strip is engaged by the recessed portion C of the locking member Cwhen the same is lifted by the latch or lever E, thereby permittin thelocking member 0 to rock on the under ace of the cross piece D.

When in position the locking member C rests upon the bottom of therecess A which is slightly lower by three-fourths of an inch, than theunder face of the locking finger B of the knuckle B. The lever E extendsup.

wardly through the slot A and its normal position in the .slot isindicated in Fig. 2, only the top of the upper end rojec'ting from theupper end of t e slot. he perforation in the upper end of the lever Ecan be used for the purpose of securing a chain, link, or rod to thesaid upper end. When it is desired to bringing t 1e shoulder E throughand out of uneou' le the cars the lever E is moved to- I the lockingmember C is again lifted, as the ward t e center of the slot A until theshoulshoulder B is in engagement with the lock C,

der E which has been in engagement with the upper wall of the recessesAclears the said'wall, and the lever E can then be lifted into theosition shown in Figs. 1 and 8,

the slot A This movement of the lever E will lift the locking member Cvertically and a distance sufficient to clear the finger B of theknuckle Band the recess C formed upon the hook member C will strike thecross piece D upon which it will rock, as the lever E is lifted and thisrocking or turning movement of the lock C will cause its hook member Cto engage the knuckle upon the rear side of the shoulder B and upon thefinger B thus throwing the finger B outwardly into osition shown inFig. 1. With the knuck e in open position and the lock in its elevatedposition the lock rests loosely upon the u per edge of the shoulder Bwhich not on y serves as a stop to prevent the knuckle being entirelydisengaged from the recess A but also prevents the lock C dropping in tosaid recess in rear of the knuckle. VYhen the knuckle is in this, itsopen position, the co- .acting knuckle carried by the other car, is alsoset in open position and the two cars permitted to come together withthe knucles in open )osition. The engagement of .the two lUHICdOS willautomatically swing the knuckle B into the osition shown in Fig. 2carrying the locking inger B back into the recess A and forcin thelocking member C back into its normal or perpendicular position, and itthereupon drops by gravity to the bottom of the recess and the shoulderE, falling below the lower end of the slot A a ain becomes lockedagainst the upper Wall of the recess A and cannot be opened until andthe knuckle fingerB fits in the space formed between the body of thelock C and the angled hook member C.

Having thus fully described our invention, what we claim as new anddesire to secure by Letters Patent, is i l. A coupler comprising arecessed head, a knuckle having a finger projecting into said head, ashoulder on said finger engaging the inner upper edge of .the recesswhen the knuckle is in open position, an angled, verticallymovable'locking member adapted to lock the knuckle against outwardmovement when the locking member is in its lowest normal position andmeans for lifting the locking member and forcing the knuckle into openposition, the locking member resting on the shoulder above mentionedwhen in its highest position.

2. Aear coupler'comprisin a coupler head having a recess formed in itsfront face and a vertical slot communicatin in its lower end with saidrecess, a pivoted knuckle having a finger adapted to work in the saidrecess, the said finger having a shoulder formed thereon, an angledlocking member resting loosely within the recess and adapted to receiveand lock the knuckle finger in a closed position,

and a lever connected at its lower end with ALBERT P. GOLDMAN.
